Paul and Max are having a beer
Max, snapping a selfie: with his beer: I'm making this NFT a smart contract. You have to sell it, and I'll get a cut, or it dies.
If my bank account goes negative, the NFT destroys itself if you don't send me more money.
Paul asks: NFTs that evolve... so you are buying a pig in a poke for way too much money and then it can get even worse?
Paul facepalms: NFTs are the Tamagotchi of the 2020s.
Max, excited: No, Pokémon! Gotta drink them all!
